The present invention relatesto rotary stud fastener installations .of the type employing a rotary stud member formed with a lateral projection, as for example, a radial pin, andy mounted in a part to be secured Vto a support, which stud member is designed upon partial rotation thereof to interlock with a socket member attached to said support.

More particularly the invention relates to novel and improved means for shiftably attaching the socket memberto the support and aims generally to improve existing attaching members for that purpose.

Further aims and objects of the invention will appear from the following description, reference being made to the accompanying drawing wherein a preferred embodiment of the invention is illustrated.

In the drawing: y

Fig. 1 is a top plan view of a fastener-secured installation embodying the invention as viewed from the female fastener side thereof;

Fig. 2 is a sectional view of the fastener instaclllation as taken on the line 2-2 of Fig. 1; an

Fig. 3 is a transverse sectional view thereof as taken on the line 3--3 of Fig. 1.

Referring to the drawing, the invention is illustrated as applied to a conventional type of rotary stud fastener installation as commonly used for connecting together cowlingand like sheets of aircraft bodies and embodying a support'I formed with an aperture 2 for receiving the stud member 3 rotatably mounted in a part 4 to be attached 'to the support I. .The stud 3 conveniently is .provided with radial arms or projections 5 adapted to engage and interlock Detroit, Mich., assignor to Corporation, Cambridge,

' (ol. .a4-221) with a cam or like seat of a female fastening.

member or socket device 6 attached to'the support I, upon turning movement of the stud, as will b readily understood.

The female fastener member or socket device may be of any of the approved forms of sheet metal devices commonly used as socket members for cowling fasteners. Preferably the member 6 application of William A. Bedford. Jr., Serial No. 420,554, nled November 26, 1941. Advantageously it is formed of a single piece of sheet metal having a base portion 8 providing a bearing section and a central vstud-receiving aperture 9. Portions of the base surrounding the aperture 9 are dished outwardly providing a raised cam seat or embossment III adapted to be engaged by the radial arms 5 of the stud 3 when the latter is rotated tainer member in such a way as the member 6 and the stud of the .ber advantageously includes a partial revolution. The female member or socket device may also be provided with integral locking means I I overlying the cam seat l0 as disclosed inthe said'Bedford application above mentioned.

According to the invention the female or socket member 6 is loosely and shiftably attached to the support I by means of an attaching or reto permit lateral shifting ofthe member 6 relative to the support aperture 2 so as to effect ready alignment between part 4 to be attached to the support. l

According to the invention, the attaching member comprises a plate member I5 having a. base portion formed with an enlarged aperture which preferably is of 'substantially greater diameter than the apertured cam seat I0. The plate memtangular central enlargement Il surrounding the aperture lliI and may be formed with lateral extensions I 8 apertured as at I9 to receive suitable fastening means 20 such as rivets for securing the attaching plate to the support. The opposite sides of the attaching member, intermediate the fastenings 20, are shaped to provide guide means 2| comprising upstanding portions 22 and laterally disposed portions 23 loosely overlying parts of the socket member 6. These guide means 2| being formed 'on opposite sides or the attaching member provide opposed channel-shaped guides for receiving the socket member. and preferably the width and depth thereof exceeds tle Width and depth of the embraced portion of the socket member so that the socket member may be shiftable laterally, transversely and longitudinally of the attaching plate. t

- Suitable means may be provided for limiting `the shiftability of the socket member longitudlnally 'in the guide and advantageously such means may comprise stop members 25 conveniently formed as ridges in the plate I5 and spaced apart a distance substantially greater than the distance between adjacent 'edges of the socket member. In this way' the socket member haslimited longitudinal 'shiftability -on the attachlng member.

In practice the attaching plate and socket member are assembled together prior to securing the assembly to the support, which may be done by riveting or otherwise fastening the attaching plate on the support so that the aperture IB thereof surrounds or is in substantial alignment with the aperture 2 of the support. The socket member is thus shiftable relative tothe a substantially recsupport aperture so that it may be readily aligned with the stud member 3 of the lpart 4 as the latter is assembled in place relative to the support l. This construction facilitates materially the assembly of the parts of the fastener together regardless of accurate pre-location of the stud and socket members of the fastening. Although I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby because the scope of my invention is best defined by the following claims.
